Definitions

  • the present invention relates to monitoring performance generally and, more particularly, but not by way of limitation, to novel means and method for reviewing the path of travel of an object or a person.
  • the present invention achieves the above objects, among others, by providing, in a preferred embodiment, a plurality of battery-operated radio frequency transmitters that are located throughout a travel route, which transmitters periodically broadcast location numbers, each transmitter having a location number uniquely identifying that transmitter and its location.
  • a radio frequency receiver is located in the object or on the person being monitored. When the receiver detects the carrier frequency of a transmitter, it activates a microprocessor which stores in memory the identification number of that transmitter and the date and time when the number was received. This is repeated within the broadcast range of each transmitter. When the receiver is taken to a home base, the memory is unloaded and the travel route that was taken can be determined together with the times the various check points were passed.
  • the transmitted signal may also include a message that the state of charge of the transmitter battery is low.
  • Figure 1 is a schematic illustration of the present invention as applied to a police car.
  • Figure 2 is a top plan view of the illustration of Figure 1.
  • Figure 3 is a top/front/side perspective view of the transmitter of the present invention.
  • Figure 4 is a top/front/side perspective view of the receiver of the present invention with a mounting bracket therefor.
  • Figure 5(a) is a schematic block diagram illustrating the components of the transmitter module of the present invention.
  • Figure 5(b) is a schematic block diagram illustrating the components of the receiver module of the present invention.
  • Figure 1 illustrates the present invention as it may be employed in the reviewing of the travel route taken by a police car 10.
  • Police car 10 has mounted on the dashboard thereof a radio frequency receiver module 12.
  • Receiver module 12 is capable of receiving a radio frequency signal broadcast from a radio frequency transmitter module, generally indicated by the reference numeral 14, fixedly mounted at a predetermined geographical location, such as on a street light pole 16.
  • Transmitter module 14 may be attached to the post by any suitable means such as metal bands 18.
  • police car 10 is shown (solid lines) moving along road 20 in the direction shown by the arrow and is shown entering the broadcast range of transmitter module 14, generally indicated by the reference numeral 22.
  • Police car 10 is also shown (broken lines) leaving broadcast range 22.
  • Broadcast range 22 has a relatively small radius which may be on the order of about 300-500 feet so as not to overlap other broadcast ranges.
  • transmitter module 14 includes a power section 30, on which is mounted a solar panel 32, and a transmitting section 34. It should be noted (Figure 2) that transmitter module 14 is mounted on street light pole 16 such that light from a lamp thereon falls on solar panel 32. It will be understood, of course, that transmitter module 14 could be mounted, as well on any other suitable structure.
  • receiver module 12 has a "power on” indicator light 40, a “receive” indicator light 42, and an identifying bar code, all on the front side thereof.
  • receiver module 12 Shown with receiver module 12 is a mounting bracket 50 into which receiver module 12 may be inserted, the bracket being permanently affixed to the dashboard of police car 10 or removably affixed thereto by means of double-sided adhesive tape 52. Disposed internally of bracket 50 at the inner end thereof is a multi-pin plug 54 which mates with a corresponding receptacle (not shown) on the rear side of receiver module 12 when the receiver module is inserted in the bracket (broken arrow). Power may be supplied to receiver module 12 through a plug 54 connected by cable 56 to the electrical system (not shown) of police car 10 or a separate battery power source (not shown) may be provided for the receiver module.
  • power section 30 of transmitter module 14 includes solar panel 32 and a battery pack 60, the latter being coupled to the solar panel so that it may be charged therewith. Both solar panel 32 and battery pack 60 are connected to provide power to a power switch 62 in transmitting section 34 of transmitter module 14, the power switch automatically determining from which source to draw power. Power switch 62 furnishes power to a timer 64 and to a power monitor 66. Timer 64 is connected to furnish power to an 800-MHz oscillator 68 and a sequencer 70, both of the latter providing inputs to an FM modulator 72 which is coupled to an antenna 74. Sequencer 70 receives inputs from power monitor 66 and from a memory circuit 76 containing a location number for transmitter module 14.
  • receiver module 12 includes a receiving section 86 and a memory section 88.
  • receiving section 86 Within receiving section 86 is an antenna 90 connected to an 800-MHz tuner 92 which is coupled to provide inputs to an FM demodulator 94 and to a carrier detector.
  • a power switch 98 is connected to receive power through plug 54 ( Figure 4) and provide power to tuner 92 and carrier detector 96, the latter being connected to provide power to FM demodulator 94.
  • "power on" indicator 40 also Figure 4) is lighted.
  • a microprocessor 100 in memory section 88 of transmitter module 14 receives a demodulated FM signal from FM demodulator 94 and receives power from carrier detector 96, both of the latter being located in receiving section 86 of transmitter module 14.
  • Microprocessor 100 also receives inputs from a real time clock 102 and from a memory circuit 104 containing an identification number for receiver module 12. Microprocessor 100 is connected to provide an output on a lead 108. Coupled to microprocessor 100 is a nonvolatile memory 106.
  • bar code 44 ( Figure 4) on receiver module 12 is read at the home base of police car 10 and entered into a main computer (not shown) at the home base along with other information such as the time and date and the police officer's badge number.
  • the main computer thus stores information specifically identifying that receiver module 12 was used by that police officer on a particular date.
  • Receiver module 12 is then inserted in bracket 50 Figure 4) in police car 10.
  • timer 64 of transmitting section 34 of transmitter module 14 causes 800-MHz oscillator and FM modulator to periodically broadcast through antenna 74 the location number from memory circuit 76.
  • the period between such broadcasts may be on the order of 4 or 5 seconds and the duration of each broadcast may be on the order of about 100 milliseconds, the former period being relatively long and the latter period being relatively short in order to conserve power.
  • carrier detector 96 in receiver module 12 will very shortly detect that an 800-MHz carrier frequency has been received by tuner 92 through antenna 90 and will activate FM demodulator 94 and microprocessor 100 which will temporarily store the broadcast location number.
  • microprocessor 100 will compare it with the first and store it in nonvolatile RAM 106 along with the identification number of the receiver module from memory circuit 104 and the time and date from real time clock 102. This procedure assures that a valid identification number is being received.
  • carrier detector 96 will detect the absence of the periodic transmissions and will remove power from microprocessor 100, which event will cause the microprocessor to store in nonvolatile RAM 106 the time and date the police car left that broadcast range. It will be understood that, as police car 10 proceeds on its rounds, it will traverse a number of other broadcast ranges of other transmitter modules and data indicative of the time it remains in each will be stored in nonvolatile RAM 106.
  • microprocessor 100 is activated, such is indicated by lighted "receive" indicator 42 ( Figures 4 and 5(b)).
  • receiver module 12 When police car 10 returns to its home base, receiver module 12 is removed from the car and inserted into a reading receptacle (not shown) to input to the home base computer the information stored in nonvolatile RAM 106. The information is then used to determine the route taken by the police car and the times it was in or between various broadcast ranges.
  • transmitter module 14 means to automatically indicate when solar panel 32 and/or battery pack 60 are becoming weak or defective.
  • power monitor 66 continuously monitors the condition of the power being supplied to power switch 62 and provides to sequencer 70 a signal indicative thereof.
  • sequencer 70 is activated by timer 64 during a broadcast interval, it alternatingly provides to FM modulator 72 the battery condition signal from sequencer 70 and the location number from memory circuit 76.
  • the demodulated signal is received by microprocessor 100 in receiver module 12, it will contain, serially, the location number of transmitter module 14 and an indication of the condition of the power source in the transmitter module.
  • microprocessor 100 will store that information in nonvolatile RAM 106. That information will be read out at the home base and a note automatically made that power section 30 of transmitter module 14 needs to be replaced or serviced.
  • a warehouse guard might be required to carry a receiver module which would be responsive to transmitters modules located throughout the warehouse. Later readout of the receiver module would determine whether the guard had made the required inspection rounds.
